Danielle Panabaker, who plays Caitlin Snow in The Flash, has a new interview up on The CW's social media channel, explaining just why she's so interested in The Flash's body.

"The scientist in Caitlin is excited to know everything that's going on in Barry's body," Panabaker said. "As a biogeneticist, she can't wait to see what's going on and figure out how his body has changed and see what we can learn from that."
